Injection molding machine ejection mechanism

The utility model relates to an injection molding machine ejection mechanism, including the ejector pin, the one end of ejector pin is equipped with the screw thread, passes through threaded connection with the connecting plate to it is fixed through the nut, the connecting plate is connected with the injection molding machine, the other end and the dismantled and assembled fixed connection of movable mould board of ejector pin, dismantled and assembled fixed connection is electromagnetism actuation or threaded connection. An injection molding machine ejection mechanism, the reset speed is controllable, factor of safety is high, the change of mould is simple and convenient. Simplify mould structure, practiced thrift manufacturing cost, there is not spring inefficacy problem in the spring that does not need to be changed, has reduced mould maintenance cost and time, safe and reliable, and the material resources of using manpower sparingly have improved production efficiency.
